A communication system automatically mutes a microphone in response to a key event detected from a coupled keyboard to prevent delivery of noise generated by the keyboard to a far end of the communication session. A timer is initiated for a time period when the key event occurs, and the microphone remains muted for the time period of the timer. The timer may be restarted to maintain the microphone mute in response to a subsequent key event detected while the timer is running. If the timer expires before a subsequent key event is detected, the microphone can be restored to its previous state (usually un-muted). The system can be applied to a computer coupled to the keyboard and a microphone and having a communication application operating on the computer. Alternatively, the system can be applied to a computer coupled to the keyboard and coupled to an external conferencing unit having a communication application.

A method and apparatus for teaching keyboarding utilizing a series of short exercises designed to present letter combinations, including word parts and whole words, that reflect both the keyboard organization, a frequent spelling combination and alphabet parts. A columns and alphabetic approach provides correct neuromotor patterning by establishing accurate brain-finger messages. The method may also be used with a technique for color-coding the fingers on each hand and their associated keys on the keyboard to provide visual stimulus to further enhance the learning process.

The invention discloses a dust remover for a computer keyboard, which comprises a device housing, a brush head and a rotating impeller. The device housing is divided into an upper housing and a lower housing, and a battery is arranged inside the upper housing. The battery is a rechargeable battery, the tail of the battery is connected to the charging socket provided at the tail of the upper casing, a switch is arranged on the surface of the upper casing, and a rotating impeller is arranged inside the lower casing. The present invention can effectively clean the dust in the dead corner under the keyboard gap through the brush head that can blow air and rotate to clean the dust. The design structure with fast cleaning speed and simple operation not only has low production cost but also has the effect of cleaning dust. Very good. It can greatly increase the aesthetics and service life of the keyboard. The rechargeable design structure and replaceable brush head can greatly save cleaning costs and waste of resources. It is very suitable for the promotion and use of computer keyboards to clean dust.

The invention relates to the field of keyboards, and especially relates to a backlight crystal key cap applied to a computer keyboard. The backlight crystal key cap comprises a key cap body and a bottom projection light source, the key cap body comprises a pedestal and a crystal cover covering the pedestal, the surface, of the pedestal, facing the crystal cover is provided with a character, and the character is formed in a way that laser can penetrate the crystal cover, and engrave the character on the pedestal to form a character pattern; or the character is formed by die injection moulding and does not need to be engraved or printed, and the pedestal and the crystal cover are made of sizing materials having different transparency and are combined to form an integral structure through double-material injection moulding integral moulding manner. According to the invention, in a conventional technology, the process that the character is achieved by being printed on the surface of the button is changed, under the condition that any printing ink is not employed, the conventional way that after monochromatic injection moulding, the character is printed and then is pasted is improved, seamless combination is achieved, the dustproof and waterproof effect is good, during the laser engraving process, the crystal cover is resistant to laser engraving and is not engraved through by laser, and laser does not engrave the crystal cover; by adjusting the power of a laser beam, the pedestal can be gasified or carbonized, and therefore a character, a symbol or a pattern can be engraved in the pedestal.

The invention discloses a stamping die for a computer keyboard. The stamping die comprises an upper die plate and a lower die plate which are oppositely arranged, wherein an upper die core is installed on the upper die plate, a lower die core is installed on the lower die plate, the upper die core comprises an upper die core plate, a plurality of stamping protruding blocks matched with keyboard keys in shape are arranged at the lower end of the upper die core plate, a groove located in the upper end of the upper die core plate is formed in the upper die plate, a pushing assembly is arranged inthe groove, the pushing assembly comprises a pushing plate capable of moving up and down, the upper end of the pushing plate is connected with a spring set fixedly connected into the groove, a plurality of pushing protruding columns movably arranged on the upper die core plate in a penetrating mode are arranged at the lower end of the pushing plate, the corresponding pushing protruding column islocated between every two adjacent stamping protruding blocks, and a limiting assembly for preventing the upper die core and the lower die core from deviating during die assembly is further arranged between the upper die plate and the lower die plate. According to the stamping die, a stamped finished product can be conveniently taken out, and the quality problem of the stamped finished product caused by die assembly position deviation is avoided.
